' This invention relates to means for removwhereby terminals that cannot be engaged from their under sides may be pulled'f'rom the postswithout damage to the battery, the

combination of such means ina small, simple 10 constructed 'unit having butone operating handle, and the provision of sucha terminal puller at an exceedingly low cost of production." Other objects will be readily apparent in the following description of one particular form of my invention, as illustrated in the accompanying drawing, in which-- j;

Fig. 1, is a fragmentaryfront elevation of my terminal puller in an operative position over a'battery; v V

Fig. 2, a front elevation of the puller alone; Fig. 3, a side elevation; a r Fig, 4, a transverse section on the line 4 4: in Fig; 1; and

1 parts throughout the several views of thedrawing. a v 1 1 form a bar 10 with bifurcated ends, in the the two jaws 11 by the pins 12. I also form a second bar 13 with similarly bifurcated ends, into which the upper ends of the jaws 11 may slidingly enter and Contact therollers 14 rov tatably carriedtherein. r

The aws 11 are each provided'with a stop lug 15 which contacts against the lower bar 10 each within the respective bifurcations to limit the outward swing of the upwardends periend of each jaw 11 has its inner edge shaped so that as the bar 13 travels upwardly away from the lower bar 10, the upper ends .of the jaws 11 are forced apart by the rollers The extreme upper ends of the jaws are in- Fig. 5, a transverse section onthe line 5 5' v bifurcations of which'are pivotally' securedpost as a means .of turning'the The lower ends ofthe jaws 11 are inturned 3 0' each to havea sharpened tooth 17.

turned a curved'portion to hook over the rs 14 and limit the upward'travel of the bar lSthereby v v j Referring to Fig. 1, it'is usually found that Go the terminal 18 is positioned on the battery 1 I d post 19 so low that there is no opening or space between the terminal 18 and the top of the battery 20.. Usually afterlong usage, theterminal 18 becomes corroded onto the post} 6 19. With myfinvention, the terminal 18 so corroded may be easily and quickly removed without 1nj ury tothe battery itself. To operate the puller, the post 21is turned to carry the bar 13 toward its lower .end 70,

down against the bar 10, whereupon the upper ends of the jaws 11 may be swung in wardly (see dotted lines, Fig. 2) to throw the teeth 17 apart. In this positionthe puller is placed over the terminal 18with the lower end of the post 15 centrally positioned on the top of the battery post 19 and the teeth 17 held in contact against the outer side of the terminal 18. Y W .8

r The post 21 is then turned to cause the bar i 13 to travel upwardly to press the'upper ends of the jaws ll'outwardly to cause the teeth 17 to bite into the sides of the terminal 18 as in'Fig.,1; At the same time the bar 13is travelling upward to spread apart the upper 8 ends of the jaws. l1, there is a vertical com? ponent lifting force applied'to theteeth 17 tending to pull the terminal 18 upwardly ofl f I I the battery post 19. Ifthe terminal hasnot started to liftby the time the rollers 14 reach t the upper inturned ends of the jaws 11 01' the lugs. 15 have contacted thebar 10, the teeth 17 have already been set into theterniinal sufliciently deep-to withstand upward pull, and continued rotation of the post 2195 will carryithe bar 13upwardly to bring the terminal 18 along therewith throughzthe 11, without causing the teeth 17 to bite deeper into the terminal 18. The terminal 18 is made'of lead andth'eteeth 17 biting into it causes no objectionable damage.

, What I lesire to secure and claim asnew is: i r c 1'. In a battery terminal puller, a pair, of .8

jaws, a-lower bar pivotally securing the aws '105 in a spaced apart relation, an upper bar, 'a post"screw-threadedly, passed through the upper barjand adapted to slidingly pass I through the lower bar,'said upper bar being' 1 associated with said jaws wherebyupward travel of said bar on said post willcausethe' lowerends of thejaws to swing toward each I by Letters Patent i v ethier and sltop means esseciated with the lower bar limiting the inward swing of the 'jaw ends. 5
